Abstract

An information recording medium wherein the key information (1) is recorded by arrangement of a unit area (1a) recorded irreversibly and a unit area (1b) not recorded irreversibly to effect the truth judgment of the medium in accordance with the result of whether or not the reproduction of the key information (1) can be effected, the information recording medium where the illegal usage of the medium is adapted to be prevented without inputting the information on the medium truth judgment into the processing apparatus by provision of the medium firm information (4), a reproducing method for the same, a truth judging method for the same, and a recording/reproducing apparatus for the same.
